Statutory Instrument of the Welsh Assembly [from Print source using APA 5th ed.]


Because the situation regarding legal references is complex, and only US law is covered in the APA Manual, the following guidance is based on the system recommended by the Institute of Criminal Justice Studies. It should not be followed by any student submitting work to the Law Department of Portsmouth Business School, and students working in other departments should consult their lecturers.

A statutory instrument is also known as an SI.

When using legislation in your work you must be certain as to whether or not you are dealing with the law as it was passed by initially, or the law as in force currently.

Standard Form

Statutory Instruments are not included in reference lists at all. However, on the first mention of the instrument a full citation is given stating:

Short title as printed on cover of the instrument (including capitalization as shown but with no italicization) Date SI number

No comma should appear between the word regulations (or order) and the date.

Thereafter the short title or an accepted/recognised abbreviation of it can be used without the date if there is no cause for confusion.


In the case of Statutory Instruments from the Welsh Assembly the word Wales is normally included in brackets in the short title unless the Act is obviously a local one.

The St Clears-Pembroke Dock Trunk Road (A477) (Sageston-Redberth Bypass) Order 2000/1172


The Single Education Plan (Wales) Regulations 2006/877

Remember after the first full citation the date and number can be omitted and the title shortened so long as separate pieces of legislation are clearly identifiable.

Citation in Text

When citing in text you need to pinpoint your specific reference within the act. Rather than use page numbers it is often easier to use the internal numbering of the act itself.

... those consulted under S6 of The Single Education Plan (Wales) Regulations include ...

If you want to refer to several sections at the same time then, for example, write

... grants as detailed in S 6, 8 and 9 of The Individual Learning Accounts Wales Regulations 2003/918

In case of amended legislation make the exact source quite clear, e.g.

... in Wales The Air Quality Regulation 1997/3043 were revoked by The Air Quality (Wales) Regulations 2000/1940


  • Legislation applying to the whole of the UK can be assumed to apply in its entirety to Wales unless this is made explicit within the Act. Some Acts apply primarily or exclusively to England and Wales
  • The National Assembly for Wales is restricted to passing subordinate legislation only. These have Statutory Instrument numbers but are also given numbers to designate them in a separate Welsh sequence (prefixed with a W). It is less confusing for referencing to use the standard Statutory Instrument number.
  • The Welsh language has official equal status with English in Wales so every Statutory Instrument made by the Assembly is officially published in both English and Welsh.
